Our software uses QR codes for inventory tracking. They're absolutely wonderful - you can store loads of data in a format that's very easily parsed by handheld scanning devices. So much data that you can completely do away with having to call out to a central database for item information, as you do with bar codes.
QR codes are great, and I never understood why they're treated as such a joke.
So, how should kids be taught? Since learning styles are a myth, would it be okay to skip in-person lessons entirely and just move everyone to individual text-based book learning?
After all, it looks like the idea that "someone might learn better in person" or "by discussing things with peers" is complete bunk, and one method should be sufficient for everyone.
